tain new and useful Improvements in Metal Car-Frames, of which thefollowing is afull,

clear, and exact description, reference being had tothe accompanyingdrawings, forming aparthereof.

My invention has relation to lmprovements 1n metal car-frames; and 1tconslsts 1n the novel construction and arrangement of parts more fullyset forth in the specification andpointed out in the claims.

In the drawings, Figure -1 is a vertical transverse section of one-halfof the frame,

is a horizontal section on the broken'line 3 3 of Fig. 2. Figrdis ahorizontal section on line 4 4: of-Fig. 5, showing the pier-section atthe=window-sill. Fig. 5 is an elevation of Fig. 4. Fig. 6 is an insideelevational detail showing connection between the inside stiffener -orside plate and the window-piers. Fig. 7 is a vertical cross-section online 7 7 of Fig. 6. Fig. '8 is an elevational detail showing connectionbetween a side post and stud and the longitudinal structural member orrunner below the line of the window-sill. Fig. 9 is a verticalcross-section on line 9 9 of Fig. 8. 'Fig. 10 is an inside elevationaldetail showing connection between the inside stiffener and the sidepost.

member and bottom sills is :strengthened by suitable studs resting onsaid sills, one in which the side posts arch towardthe carlines,

thereby reducing in a measure the lateral thrust ontheposts, .one inwhichthe body of the carline conforms-to thelcontourofthe roof ofthecar, one inwhich theconnection between the carlines-and the.archedextension ofthe posts isreinforced by thedecksill, one makingspecial provision for stiffening the-postsat the bases ofthearched-extensions, and one possessing further and otheradvantages-better apparent from a detailed description. of theinvention,-which' isas follows:

Referring to the drawings, 11- represents the basal longitudinal or sidesill, and 2 the. crosssill, connected by angle pieces 3 and-otheriwisebound and strengthened within.the lim-' its of thecar-frameinanyqmanner, nothere necessary tomention, as thepresent-invention is not articularly. concerned with these T e side. ofthe car-frame is composed of a longitudinal structural member. or runner4, beingvirtually a. Z-bar, as shown, and occupying a plane just belowthe .win- (low-sill. To the lower horizontal flange. of the Z-bar aresecured a series of studs 5,.being -Ts in cross-section, the flanges ofthe TS being directed outwardly andthewebs-inwardly. It maybe statedinpassingzthat the section showing these studs in Fig. 3 outsthenearrwall or that partlybroken away in Fig. 2. To the flanges of thestuds issecured a coverin of quarter-inch plate' 6, the joints between te sheets being covered bysuitable batten-strips 7, as shown. Theplate-6-and battens 7 cover the face of the web. portion of the Z-bar, asclearly indicated in the draw- The connection between the studs andtherunner 4 is made, asshown in" Fig.8,- by means of castings 8.Superposed directly over the studs 5 and carried-by the ,lower flange ofthe Zbarare the posts 9,-.,which are likewise -Ts, the bases of-theaTsbeing secured to the Z-barl by castings or shoes. 10, an ironfiller-block 11 being interposed between 'the post and theweb of.thezebar, Figs-8, 9.

The posts 9 mark theexteriorboundaries'of any pair of windows, the.interior boundaries of such pair-being markedabythepiers 12,

-which are angle-bars disposed pairs, one

extension, the straight'portion being substantially tangent to thecurvature of the curved' 1 extension, the free ends of the several postsand piers being secured to the lower ends of the carlines-14, Figs. 12,13, along Whose 1nner faces are in turn disposed the channeldeck sills15, Figs. 1, 2, 12.

An inspection of Figs. 4 and 9 discloses the "fact that thecross-section of the pier 12 is equal to the width of the flange of theZ-bar supporting it; but the cross-section of the post 9 being less thanthe width of the supporting-flange of the same Z-bar the difference iscompensated by the filler 11, so that all the posts and piers may bedisposed on the Z-bar in the same plane, the filler 11, in ef--fect,.forming an extra thickness for the flange of the T 9.

Disposed along the bases of the curved extensions of the several postsand piers and secured to the inside of the straight portions thereof arethe inner stiffeners or side plates 16, the manner of securing them tothe piers being indicated in Figs. 6 and 7 and the manner of securingthem to the posts being shown in Figs. 10 and 11. Between the piers isreceived a casting 17, to which the vertical member of the plate issecured, and to the webs of the posts 9 are secured castings 18, towhich the corresponding vertical members of the side plate are secured.The outer stiffener 16 is of course conveniently secured to v the outerflange portions of the several posts and piers, requiring no specialcastings for its 1 support, since the outer flanges of the posts andpiers are disposed in the same plane and already form a continuoussurface, to which such outer stiffener may be secured. Below thestiifeners 16 are secured the upper plates 6, as fully indicated inFigs. 1 and 2. The carlines 14 are curved angle-bars, as shown, being ofconvenient form cross-sectionally to afford support for the deck-plates19 at the corner formed between their straight terminals and the middlecurved or arched portions thereof. To aflord the proper support for theoverhan ing portion or eaves of the roof, the vertica flanges of thecarlines have I secured to them the outwardly-projecting arms 20, whosefree outer ends carry an outer angle-piece or stiffener 21.

The posts and piers referred to serve the same function, being allvirtually and generically posts, though piers is used to distinguish theparticular osts between each pair of windows, and un ess specificallydesignated as piers the term posts in the claims is to be understood ascovering either or both. The runner or Z-bar 4 in eflect shortens whatwould otherwise be a post (or pier) of substantially the full height ofthe car were such post to start from the floor of the car. The studs 5,however, reduce the length of the posts, thereby insuring for them agreater stiffness and power of resistance and confining the center ofmoments to the plane of the Z-bar in the event the posts are subjectedto any bending strain. The studs, too, being comparatively short couldnot suffer much under such a strain, and in case of accident orcollision the runner or Z-bar 4 would act as an effective barrieragainst any tendency on the part of the car to colla se.

In Fig. 2 a small section of the woo work is shown,- but since myinvention is confined to the frame the covering therefor is merelyindicated in dotted lines in Fig. 1. Such portions of the structure towhich no reference is herein made are either old or well known and fullyunderstood in the art, so that a description thereof is hereunnecessary.

The Z-bar is eminently adapted not only for the support of theposts,-piers, and studs, as described, but the upperoutwardly-projecting flange thereof is utilized for the support of thewooden sill S, Fig. 1, the latter being additionally supported on theinside by a wooden block S, interposed between the sill proper and thelower flange of the Z-bar.

From the specific arrangement of posts and piers as shown each pair ofpiers is bounded bya post, one on each side. Thisresults inthe formationof a pair of carlines extending from the piers with a carline on eachextending from the posts aforesaid.

Having described my invention, what I claim is- 1. In ametal car-frame,a series of studs, a longitudinal runner or structural membersurmounting the same in a plane below the line of the window-sills,'anda series of posts projecting upward from said structural member, saidposts having upper inwardly-curved extensions, substantially as setforth.

In a metal car-frame, a longitudinal 2- bar structural memberdisposed on a line below the window-sills, pairs of angle-iron piersprojecting upward from the lower flange of the Z-bar, T-posts disposedon opposite sides of the angle-iron piers, and studs disposed below theZ-bar and secured to the under surface of the lower flange of the Z-bar,and distributed, one stud beneath each post, and one stud beneath andbetween each pair of piers, substantially as set forth.

7. In a metal car-frame, a longitudinal runner of Z-bar constructiondisposed below the line of the window-sills of the car, a series ofT-studs projecting downwardly from the lower flange of the Z-bar, and ametal cover-plate secured to the flanges of the T s, the webs of thelatter being directed inwardly or toward the interior of the car,substantially as set forth.
